Abstract (en)
[origin: EP0123902A2] An improved determination of peroxidase activity by end dilution titration is carried out with a benzidine derivative of the general formula I <CHEM> where R1 stands for a hydrogen atom, a halogen atom, an amino group, a (C1-C4) alkyl group, a (C1-C4) alkoxy group, a carboxy group, a sulfo group or a carboxypropyloxy group and where R2 stands for a hydrogen atom, a halogen atom, a (C1-C4) alkyl group, or a salt of this benzidine compound, in the presence of a non-chromogenic or low-chromogenic phenylene derivative of the general formula II <CHEM> where R3 and R4 are equal or different and stand for a hydroxy group or an amino group, a (C1-C4) alkyl amino group or a benzylamino group.
